I have a Grandland X 1.5 CDTI TECH LINE, and when I go over a grid, pot hole, man hole cover, I get a wobble on the rear end, it may be better described as a swaying motion. The car otherwise is solid on the road and holds the road well apart from this. Anyone had any similar experience? I did see a car review which stated that it has a very hard and stiff ride, I’ve found it ok but could this be the cause.
